Lead-free ferroelectric relaxor ceramics in the BaTiO3-BaZrO3-CaTiO3 system

Jean Ravez,   Cédric Broustera  and  Annie Simon  

Abstract

Relative permittivity studies of ceramics with a variety of compositions in the BaTiO 3 -BaZrO 3 -CaTiO 3 system showed some of them to be ferroelectric relaxors at temperatures close to 295 K. Such a favourable effect is due to the Ca 2+ for Ba 2+ cationic substitution. In addition a spontaneous classical ferroelectric-relaxor ferroelectric transition was evidenced. Some of these new compositions are of interest for applications (dielectrics for capacitors, actuators) since they are environmentally friendly.
